Summary

collision_resolution handles key conflicts in hash_tables. A collision happens when two keys map to the same bucket. There are two main strategies: separate_chaining and open_addressing. In separate_chaining, each bucket keeps a linked-list of entries. In open_addressing, probing finds another slot using linear_probing, quadratic_probing, or double_hashing. Track the load_factor to keep operations fast. If it gets too high, do a resize and rehash. A good hash_function reduces collisions.
